What it's used for

  • Lining internal stud partition walls in new builds and refurbishments
  • Fixing to ceiling joists as a base for skim plaster or textured coatings
  • Dot and dab application direct to masonry walls as a dry lining solution
  • Infill panels within metal frame systems in commercial fit-out work

Fitting and handling

Store boards flat and off the ground in a dry, ventilated space before installation, keeping them away from damp conditions which can cause the core to soften. Fix to timber studs or metal framing at no more than 600mm centres using appropriate drywall screws, or use a suitable bonding compound for dot and dab to masonry. Once fixed, fill screw heads and joints with jointing compound before applying a skim coat or finish of your choice.

FAQ

What is the difference between square edge and tapered edge plasterboard?

Square edge board has flat, unrecessed edges on all four sides and is designed for use where the full surface will receive a skim coat of finish plaster. Tapered edge board has recessed long edges so that jointing tape and compound can be feathered flush for a seamless, paint-ready surface without full skimming.

Can 12.5mm plasterboard be used on ceilings?

Yes. 12.5mm is a standard thickness for ceilings where joist centres are at 400mm or 600mm. For spans beyond 600mm or where additional acoustic or fire performance is needed, a thicker board or a specialist product should be specified instead.

How do I cut plasterboard cleanly on site?

Score firmly through the paper face with a sharp knife and straightedge, then snap the board away from you over the scored line. Run the knife along the back paper to separate the cut. A plasterboard saw can be used for internal cuts and cut-outs around sockets or switches.

Excellent Comfort and Great Value for a Home Office
Color: Elegant Grey, Color: Elegant Grey
I am extremely happy with this office chair and feel it offers excellent value for the price. The chair was easy to assemble, and all the parts fit together perfectly. Once assembled, it feels sturdy, stable, and well-made. The high-back design provides outstanding support for my back, neck, and shoulders. The seat cushion is thick and comfortable, making it easy to sit for long periods while working, studying, or gaming. The padded headrest adds extra comfort, and the faux leather material looks stylish and gives the chair a premium appearance. One of my favorite features is the flip-up armrests. They are comfortable to use and make it easy to slide the chair under my desk when I need extra space. The height adjustment, smooth swivel, and rocking function all work well and allow me to find the perfect sitting position throughout the day. The chair arrived exactly as described and exceeded my expectations in both comfort and appearance. It looks great in my home office and has made long work sessions much more enjoyable. If you're looking for a comfortable, attractive, and affordable office chair, I highly recommend this product. I would definitely purchase it again and would gladly give it five stars.

Comfortable and Stylish Office Chair
I’ve been using this chair for my home office, and it’s been very comfortable. The high back provides good support, and the lumbar support helps reduce strain during long hours at my desk. The leather looks nice and gives the chair a professional appearance. I really like the flip-up armrests because they make it easy to slide the chair under the desk when not in use. The rocking function is a nice feature for relaxing during breaks, and the chair rolls and swivels smoothly. Overall, it’s a comfortable, well-made office chair that looks great and provides excellent support for everyday work.
